Breaking seed dormancy takes time, and may require exposure to specific environmental conditions before germination. One common requirement is exposure to a chilling period. The artificial exposure of seeds to a period of low temperature in order to stimulate germination is called stratification.

Genetic analysis has identified the crucial role of ABA in seed dormancy, as well as the requirement for gibberellins (GAs) in germination (Koornneef and Karssen, 1994 ), mainly using Arabidopsis because of its excellent suitability for genetic and molecular studies (Koornneef et al., 1984 ), and because its...
